T2 Thermocouple Alloy Rod (Ni95/(Al+Mn+Si) 5)

Formula: Ni 95/(Al+Mn+Si) 5
Form: Rod
Material: T2 - Thermocouple Alloy
Commodity: Alloys
Hazard Pictogram: GHS07, GHS08
T2 Thermocouple Alloy Rod (Ni95/(Al+Mn+Si)5) is designed for precise temperature measurement in high-temperature industrial and research environments. Composed of 95% nickel with aluminum, manganese, and silicon, this thermocouple-grade alloy exhibits high resistance to oxidation, thermal drift, and corrosive atmospheres, making it suitable for Type N thermocouple systems operating above 1000°C. It is widely used in industrial furnaces, aerospace engine testing, and materials science laboratories, where reliable temperature readings are required for process control, thermal profiling, and experimental validation. Its long-term stability in oxidizing and inert atmospheres supports accurate measurement in metals processing, energy system monitoring, and high-temperature calibration setups.
